MECHANICAL MOVEMENT.

Application led September 19, 1919. Serial No. 324,773.

To all whom it may concern.'

Be it known that I, VICTOR R. DESPARD, a citizen of the United States,residing at Hinsdale in the county of` Du Page and State of Illinois,have invented a certain new and useful Improvement in MechanicalMovements, of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this s ecication.

My inventionrelates to switc mechanisms .and has to do more particularlywith lever operating mechanisms, being directed to an improved form ofswitch operating lever and a flexible operating connection therefor.

In connection with switches such as are ordinaril employed for lampsockets and similar e ectrical circuits universally mounted operatinglevers are provided from which a cord or pull chain may extend foroperating purposes, or in which the lever itself may be grasped foroperation. In connection with devices of this character I have provideda simple and effective lever and link or connection which may be readilyassembled, cheap to manufacture and positive in operation. In theaccompanying drawing I have illustrated one form of my invention inwhich i Fig. 1 is a, section through a switch mechanism provided with myimproved operating lever and connection;

Fig. 2is a perspective view of the lever detached and the chain holdingcap therefor; and

Fig. 3 is a top view of the pull chain, link clip, and link, and switchoperating element removed from the switch;

Iig. 4 is a perspective view of the link clip, an

Fig. 5 shows the universal lever tilted to an operating position. Y

Referring now more in detail to the construction illustrated, itcomprises a tubular lever 5 provided with a flanged head 6 adapted toride upon a face on the frame 7 which carries the switch mechanism. Thelever 5 shown is universally mounted in that it may be tilted in anydirection and also moved lineally, that is, by a direct pull. The saidlever 5 has an opening at its free end 8 against the outer end cf whicha link of the pull chain 9 rests. The pull chain 9 is connected througha link clip 1() to an inner link connection l1 heavier than the ing thesmall end of the connection 11 through an openin in the end of theconnection 12, the en arged head of link 11 being supported by the yokeof 12.- In order to insert the outer chain 9 into the lever 5 I providean openin 15 in the side of the lever so that the c ain 9 may be pulledtherethrough and when properly adjusted pulled over into the centralposition as shown in Fig. 1 and the cap 16 is then pressed over the endof the lever 1() to cover the opening 15 and hold the chain 9 in place.

The inner end of the link 11, as already. stated, is connected to aswitch operating connection 12 pivotally connected to a hookedintermediate member 18 which is connected by a spring 19 to the switcharm 20. Thus successive actuations of the operating lever 5 will effectreciprocations of the Switch arm 20. That is, assuming the mechanism isin the position shown in Fig. 1, the first pull upon lever 5 to a tiltedposition as in Fig. 5, will shift the switch arm 20 to its alternateposition and then ipon :release of the lever 5 itis pulled back to itsnormal position by operation of the spring 19 which also shifts theintermediate link 18 to its alternate position so that its lower hooksare in engagement with the lower arm of the switch frame. i

In assembling the lever and link mechanism, the switch mechanism is ofcourse out of the shell 21 and cap 22 and the switch frame is at thistime out of the insulating mounting blocks 23, 24. The lever 5, linkclip 1() and chain 9 are all disconnected and free from the switch. Link11 has been'inserted through the connection 12 as in Figs. 1 and 3. Thethin arm 10a of clip 10 is now inserted through the hole in the end oflink 11 and moved to its positions in Figs. 1 and 3. The end ball ofpull chain 9 is now sprung into the end of the clip 10 and the lever 5is now put in place by passing the chain through the side opening 15.

The parts are so proportioned that a slight pull on 4the chain isnecessary to have a ball rest against the outside end face of the lever5 under tension of spring 19. Cap 16 is now forced overthe end of lever5.

The parts 5, 9, 10, 11, 12 are now held together and the lever 5 may betilted in any direction, the rounded inner end of clip 10 riding on therounded face of the seat carried by the switch frame 7( The parts mayalso be readily separated when desired.

Although l have shown and described my invention in connection with aparticular kind of switch mechanism, it is to be understood that it maybe applied to othertypes of switches and I also contemplate makinchanges and modifications therein so that do not desire to be limited tothe exact structurel shown and ldescribed but aim to cover all thatwhich comes within the spirit and scope of the appended claims.

What I claim as new and desire to` secure by Letters Patent is:

1. Operating mechanism for switches comprising a tubular operating'leverhaving an lnturned Harige at one end provided with an opening throughthe side of the lever connecting with an opening through the ianged end,a ball chain passed through the side opening of the tube and a ball linkof which engages the lever ange to support the chain, and means forholding the chain in its supported position.

2. An article of manufacture comprising a tubular lever having aninturned flange at one end and provided with a central opening throughthe ange connected with an enlarged opening through the side of thelever, said openings being adapted to receive and support a ball chainat the flange opening, together with a cap for holding such a chain inits supported position.

3. Switch mechanism comprising a switch movement having a frame, a seaton the frame, a lever having a portion engaging the seat to tilt thereonin any direction, and a connection extending from the lever through theseat to the movement, said connection comprising a retaining clipreadily removably held in the lever and a substanmaaien tially rigidlink pivotally connected at one end to the movement and pivotally'connected at its other end to said retaining clip.

4. In a switch, switchmechanism, a tubular operating lever for saidmechanlsm having an inturned interrupted iange at a :tree end, a memberupon which said lever is ada ted to tilt in any direction, a clip insidesaidplever, a connection from the clip to the mechanism, an operatingchain connection from the clip extending outwardly through the end ofthe lever hooked over the inturned flange thereof, and a cap for thelever encircling the chain and having an inturned flange to hold thechain in engagement with the lever iange.

5. Operating mechanism for switches com-A prising a ball chain, a leverhaving a free operating end, said free end having an inturned flangethereon, and being provided with an opening therein, said lever beingprovided with an opening through the side thereof connecting with saidend opening, through which a ball of .the .chain may be inserted andmoved into holding engagement with said Bange and a cap for the end ofsaidlever. y

6. perating mechanism for'switches comprising a switch frame, a tubularlever, means for supporting said lever against the frame, means on saidframe upon which said lever is adapted to 'tilt in any direction, switchmechanism, a link extending from the switch mechanism toward the lever,a ball ended pull chain extending into the free end ot' the lever, alll-shaped spring link clip connecting theJ link and chain, one arm ofthe clip passing through the link and the free ends of both armsgrasping the ball end of the pull chain.

7. The combination with a switch mechanism of a hollow operating leverfor said mechanism and a connection extendingfrom said lever to saidmechanism comprising a retainingv clip mounted in said lever, and a linkpivotally connected at one end to the switch mechanism and at the otherend to said clip and a chain extending into said lever and connectedwith said clip.

In witness whereof, l hereunto subscribe my name this 13th day ofAugust, A. D.

VICTR R. DESPARD.
